worm gear set

Note: Because the effectiveness of a worm gear drive depends upon the lead angle and number of starts on the worm, the ratio ought to be kept low. To perform correctly, worms and worm gears working together will need to have the same diametral pitch and threads.

EP Gear offers worm gears produced from a variety of materials, such as acetal, minlon, bronze, and cast iron to suit your application’s requirements.

The pinion meshes with the teeth of the worm gear at 90 degrees, and motion is transmitted to the worm wheel when the worm pinion is rotated. Because the pinion is definitely captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm established can be modified by changing the amount of teeth on the wheel or changing the amount of begins on the pinion.
When used in combination with EP Gear worms, EP Gear’s worm gears provide effective power transmitting in applications requiring high-ratio speed reduction in a restricted space using right angle (90°), nonintersecting shafts. They are also the smoothest, quietest form of gearing when properly applied.

Just how do Worm Gear Pieces Transmit Motion?

A worm gear set is a couple of gears consisting of a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is required and space is bound.
